Cuckoo Call Dates

WWF Hong Kong is trying to gather data/information concerning the impact of climate change on Hong Kong's natural environment. Initial searches through scientific literature have turned up very little useful data.

A potential indicator could be date changes associated with the call of common birds each spring i.e. are calls being heard earlier each year over the last 20 years? Of the more vocal and easily distinguishable species, Cuckoos seem to be the most commonly reported in Hong Kong each year.

From the BBS postings this year it would seem the earliest Common Koel call heard was 3rd February at Tsing Yi. Although there are no postings for Plaintive Cuckoo I heard one call on 2nd March at the Mai Po car park.

I would be grateful if any HKBWS member could help WWF by providing dates of Cuckoo calls that they know about from previous spring periods. Please post replies below.

Many thanks,

世界自然基金會香港分會現正收集關於「氣候轉變對香港自然環境影響」的數據。初步查閱科學文獻只得出極少有用並可信的數據。

其中一項有用指標是每年春季常見鳥類開始鳴叫的日期變化，如：在過去20年，鳥類開始鳴叫的日期正逐漸提早。在香港各種常見鳴鳥中，杜鵑科雀鳥的叫聲最為容易辨認和最常被報告。

從今年新聞組貼文所見，最早聽到的噪鵑鳴叫日期是2月3日，於青衣。雖新聞組上沒有關於八聲杜鵑的貼文，本人於3月2日曾在米埔停車場聽到過。

希望各觀鳥會會員可協助提供過往各年春天杜鵑科雀鳥開始鳴叫的日期，本人不勝感激。請把相關回覆張貼在下。

謝謝！

[size=18][u][b]Cuckoo Call Dates : Spring 2008[/b][/u][/size]

Thank you to those people who provided dates for cuckoo calls last year.

For the coming 2008 spring period it would be great if we could continue this form of monitoring and once again I ask members to kindly report dates of first heard cuckoo calls on the BBS. Please note it is only the date of the first call for each species which is needed; Common Koel, Plaintive Cuckoo, Large Hawk Cuckoo, and Hodgson's Hawk Cuckoo.

If any member can provide call dates for any of the years between 1990 to 2003 it would be much appreciated.

Many thanks,

Also A large Hawk Cuckoo in Tai Mei Tuk calling on 11 March 2009....4:55a.m.!!

I could pretend to be first by claiming an earlier time (I was previously vague by only saying 'morning'!). But in fact, it was about 10.00!

It's interesting that the first individuals should turn up at widespread locations on the same day. 11th March also seems to be the earliest date in 2007.

My first LHC this year was 27 Feb at 6.30 am here at Hing Keng Shek, Sai Kung. I was setting off on a walking and camping trip to the Route Twisk/Tai Lam Chung area and there was also one calling at Tin Fu Tsai on the evening of 27th.

It seemed quite expected to me, in view of the warm and humid conditions.

Bizarrely, I don't think I've heard a Koel yet, though they are very common usually both where I live and work.

Hodgson's Hawk Cuckoo at TPK on 11th April 2009. Apparently it was also calling a few days before this.
